Iyo Mechanics uye Kushanda kweHPGR

Nhanganyaya:

High Pressure Grinding Rolls (HPGR) yakawana kutariswa kwakanyanya muindasitiri yezvicherwa neyekugadzira zvicherwa seimwe nzira yekupwanya kwechinyakare nekukuya nzira. HPGR tekinoroji inopa akawanda mabhenefiti, anosanganisira kuvandudzwa kwesimba rekushandisa, kuderedzwa kwemitengo yekushanda, uye kukwidziridzwa kwemhando yechigadzirwa. Ichi chinyorwa chine chinangwa chekupa kunzwisisa kwakadzama kwemakanika uye kushanda kweHigh Pressure Grinding Rolls.

1. Nheyo yeKushanda:

HPGR inoshanda pamusimboti wekushandisa yakanyanya kudzvanywa pamubhedha weore kana zvinhu zvekudyisa. Izvo zvinhu zvinodyiswa pakati pematanho maviri anotenderera-anotenderera, ayo anomanikidza zvakanyanya pane zvimedu. Nekuda kweizvozvo, iyo ore inopwanyika uye inoiswa kune yakakosha huwandu hwe inter-particle breakage.

2. Mechanical Design:

High Pressure Grinding Rolls ine ma rolls maviri ane inosiyana kumhanya uye dhayamita. Mipumburu yakashongedzerwa neinochinjika kupfeka-inodzivirira lining, iyo inovimbisa kusimba uye inoshanda particle comminution. Mukana uri pakati pemapumburu unogona kugadziridzwa kudzora saizi yechigadzirwa.

3. Maitiro ekushanda:

Maparamita akati wandei anokanganisa mashandiro eHPGR. Makiyi ekushandisa ma paramita anosanganisira kumhanya kwe roll, roll dhayamita, saizi yekudyisa, uye kushanda nesimba. Kukwenenzvera aya ma paramita kwakakosha kuti uwane yaunoda chigadzirwa mhando uye nekuvandudza simba rekuita.

4. Particle Breakage Mechanism:

Iyo yakanyanya kudzvinyirirwa inoiswa nema rolls inotungamira mukutsemuka kwechidimbu kuburikidza nemaitiro maviri makuru: compression uye inter-particle abrasion. Kudzvinyirirwa kunoitika kana zvinhu zvakavharirwa pakati pemapumburu uye zvichiiswa pasi pekumanikidzwa kwakanyanya, zvichiita kuti iputse. Inter-particle abrasion inoitika kana zvimedu zviri mumubhedha zvinosangana, zvichitungamira mukuputsika.

5. Particle Bed Formation:

Kuumbwa kwemubhedha wepakati kwakakosha pakushanda kwakanaka kweHPGR. Iyo yekudyisa zvinhu inofanirwa kugovaniswa zvakaenzana pahupamhi hwema roll kuti ive nechokwadi chekumanikidza yunifomu inoshandiswa kune zvimedu. Tramp zvinhu kana oversized zvimedu zvinogona kukanganisa mubhedha uye kukanganisa HPGR kuita.

6. Kushanda Kwesimba:

Imwe yemabhenefiti akakosha eHPGR tekinoroji ndeyekuvandudza kwayo simba rekushandisa zvichienzaniswa neakajairwa kugaya maseketi. Iyo yakanyanya-kudzvanya inter-particle breakage mechanism inopedza simba shoma kana ichienzaniswa nekukanganisa uye abrasion maitiro ezvakajairwa macrusher uye zvigayo.

7. Zvikumbiro:

Tekinoroji yeHPGR inowana mashandisirwo akapararira mumaindasitiri akasiyana, anosanganisira migodhi, simende, uye akaunganidzwa. Inowanzoshandiswa pakugadzira matombo akaomarara akadai semhangura, goridhe, uye iron ore. HPGR inogona zvakare kushandiswa senzvimbo yekugaya pamberi pemagayo ebhora kuderedza kushandiswa kwesimba.

Mhedziso:

High Pressure grinding Rolls (HPGR) inopa imwe simba-inoshanda uye inodhura-inoshanda kune yechinyakare kupwanya uye nzira dzekukuya. Kunzwisisa mechanics uye kushanda kweHPGR kwakakosha kuti uwane kuita kwakaringana uye nekuwedzera mabhenefiti eiyi tekinoroji. Nekutsvagisa nekusimukira kuri kuramba kuchienderera mberi, tekinoroji yeHPGR inoenderera mberi, ichivandudza magadzirirwo ezvicherwa mumaindasitiri akasiyana.
